Data used in an Appian application must originate from a relational database.

• A. True
• B. False
• C. Only from relational databases
• D. It must originate from a cloud database

Answer: (B)

Data used in an Appian application does not have to come from a relational database. Appian is designed to integrate with multiple data sources, not just relational databases. You typically use a data store to map to tables in a relational database for persistent, structured data, but you can also pull data from external systems via connectors (such as REST or SOAP web services), import data from files (like CSV or Excel), or use data stored directly within Appian during a process (constants and variables). Because of this flexibility, the statement is not correct: data in an Appian app can originate from various sources, not exclusively from relational databases.
